Abstract: An isolation mounting system for disk drive and other storage modules in which the operating unit (e.g., a disk drive) is locked more firmly into its operating position. During shipping and installation the lock is disengaged to allow full use of the elastomeric or other shock mounting system. Thus, the storage module of the present invention simulates a hard mount system during operation and a soft mount system during shipping and handling. A data storage module constructed according to one embodiment of the invention includes a data storage device, typically a disk drive, shock mounted in a housing and a lock selectively engagable between the data storage device and the housing. The lock is operable between a first disengaged position in which the lock does not restrict movement of the data storage device within the housing and a second engaged position in which the lock restricts substantially all movement of the data storage device within the housing.

Abstract: A storage enclosure is provided for electrical/electronic components. The storage enclosure includes an enclosure, an EMI barrier, air flow inlet apertures and exhaust air flow apertures. The enclosure has at least one wall configured to house an electrical/electronic component. The EMI barrier wall has air flow apertures sized sufficiently small to prevent passage of undesirable relatively high frequency EMI/RFI emissions. The barrier wall is supported internally of the enclosure and is configured to subdivide the enclosure into a component enclosure and a cooling fan module enclosure. The air flow inlet apertures are provided in the component enclosure to draw cooling air into the component enclosure and cool components contained therein. The exhaust air flow apertures are sized larger than the EMI barrier apertures and the air flow inlet apertures, and are provided in the cooling fan module enclosure to expel cooling air from the cooling fan module out of the storage enclosure.

Abstract: A disk drive crash stop/actuator latch combines a crash stop structure with a detent actuator latch which is engaged and latched in a selected radial limit position of the actuator and which is released by the simple expedient of pulsing the actuator motor. The detent actuator latch has a flexible cantilever latch arm secured at one end to the disk drive base. A crash stop face on the distal end of the cantilever latch arm is impacted by a surface on a catch member on the actuator in the radial limit. The cantilever latch arm is bowed between its ends to reduce long column stability to slightly yield to compression loads due to actuator impact. The crash stop face and the surface of the catch member on the actuator are in contact when the detent actuator latch is engaged. A pulse generator coupled to the actuator motor pulses the actuator motor in a sense to drive the actuator away from the crash stop face, overcoming the restraining force of the engaged detent actuator latch.
